There are a few different ways that conference participants can contribute:

Share digitized collections items. Work for a GLAM institution with digitized collections? Bring a few items on a flash drive that you would like to include in the scavenger hunt. Files should be in .jpg, .gif, or .png format, less than 2MB in size, and optimally around 640 pixels in width. For more details on these requirements, visit this page.

Write clues. During THATCamp, stop by the project table to brainstorm scavenger hunt clues that match the collections items people have shared.
